Neuroticism drives insomnia; anxiety treatment may improve sleep

A new study reveals that 61.7% of insomnia cases are linked to the personality trait of neuroticism, suggesting a strong connection between anxiety and sleep difficulties. Researchers found that insomniacs exhibited significantly higher levels of neuroticism, characterized by anxiety, worry, and irritability. This study, published in the Journal of Sleep Research, highlights the need to address anxiety in insomnia treatment. The findings suggest that personalized treatments, including therapies and medications targeting anxiety, may improve insomnia outcomes. Current treatments include sleep medications and cognitive-behavioral therapy.
